On Monday, Renaldo biked 1/2 of the way around the lake. How many miles did he ride?

Step-by-step explanation:

For this exercise let "x" represents the amount of miles that Renaldo biked On Monday around the lake.

You need to analize the information given in the exercise.

You know tha the perimeter of that lake is:

Knowing that on Monday Renaldo biked of that perimeter, you can write the following equation:

Now you must subsitute the perimeter of  the lake into the equation:

And finally, you must evaluate in order to find the value of "x".

You get that this is:

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
